Labor Secretary Lori Chavez-DeRemer announced her resignation from the Biden administration this week, according to multiple news reports.

The announcement came as several news outlets reported that an internal investigation was underway regarding alleged workplace misconduct involving the labor secretary. The specific nature of the allegations has not been publicly detailed.

Chavez-DeRemer, who previously served as a Republican congresswoman from Oregon, was confirmed as labor secretary in early 2023. Her tenure oversaw several key labor policy initiatives during her time in the role.

The Department of Labor has not issued an official statement regarding the circumstances surrounding her departure. CBS News has not independently verified the allegations that reportedly prompted the internal investigation.

No timeline has been provided for when Chavez-DeRemer's resignation will take effect or who might serve in an interim capacity. The White House has not yet announced plans for nominating a replacement for the position.
